Sir – Our great country is known for producing talented inventors and engineers. Therefore, it is high time that we took control of the wind farm industry which presently relies on an inferior Danish import.

The turbines that we import are not efficient enough, damage wildlife and rely on subsidies. However, the principle of wind power is a good one if we get the technology right. There are many new designs for turbines that are far more effective than the present windmill blade model.

For instance, there is a new tunnel design that produces 600 per cent more electricity. The wind’s kinetic energy is amplified through a funnel design that is friendly towards wildlife as there are no dangerous blades.

Instead of snatching bits of energy from the wind as it passes through the blades of a rotor, wind is captured with a funnel that accelerates the flow.

This design can be scaled down and is half the size of present turbines. The funnel works on winds of 2mph. Therefore, we need to stop spending money on an inferior Danish import and start investing in superior-engineered wind turbines that deliver good value for money. The Government has recently stated it will build no more new onshore wind farms.

This decision may be a blessing as it gives time for a caveat to explore far superior turbines. Wind energy is potentially a godsend for clean cheap energy if we adopt the new engineering ideas.
